The Unitary Democratic Coalition (Portuguese: CDU – Coligação Democrática Unitária, CDU) is an electoral and political coalition between the Portuguese Communist Party (Portuguese: Partido Comunista Português or PCP) and the Ecologist Party "The Greens" (Portuguese: Partido Ecologista "Os Verdes" or PEV). The coalition also integrates the political movement Democratic Intervention (Portuguese: Intervenção Democrática or ID).

The coalition was formed in 1987 in order to run to the simultaneous legislative election and European Parliament election that were held on July 19 of that year. It achieved its best result in the 1987 elections both nationally and locally. From 1991 until 2019, the party consistently won between six and ten percent of the national vote in elections to the Assembly of the Republic until 2022 and 2024, in which the coalition dropped below 5% nationally for the first time. The coalition supported the minority Socialist Costa Government from 2015 until 2019 with a confidence and supply agreement.
